The recording section to be used is selected from Go, 200, and 306 as follows. That is, the specified number of original pages to be copied and the specified number of copies N specified by the operator are read (step 81), and when the number of original pages is 1, the process proceeds from step S8 to rY]c8JO, and the number of copies is determined. Recording is performed by selectively driving only one unrelated recording unit (step 810G).

In selecting the recording section, the unit indicator 216 in the control path 18 is used as described above. The unit indicator 26 has a ternary counter, 3

Further, in step 84, when the number of copies is 1, the process advances to step 8400, where the indicator 26V* is deposited (step 8400-1), recording is performed in the designated recording section (step 8400-2), and the indicator 26 Step 7rlJ (step 840G-3)
).

Hereinafter, the apparatus of the present invention in which recording units Zoo, 200, and 300 are selectively driven will be described.
Let's take the case of copying as an example. will be explained in detail.

The page dial 21 on the operation panel 19 is set to "2", the number of copies dial 20 is set to "5", and the copy button 22 is operated. In step 780 shown in FIG. 4, the control circuit 18 determines that the start button 22 has been pressed and proceeds to step B1, where the specified number of pages L=2. Specified number of copies N=5
is read and the values are stored in the page counter 25 and copy counter 24, respectively. In step S2, it is determined whether the content of the page counter 21s is "1". In this example, the page counter 25F - the number of stored pages is "
2", the process advances to step S3, and the number of copies counter 24 is
It is determined whether the number of copies stored in is "3" or more.

In this example, an affirmative determination is made (N=5>3), and step 82
Proceed to 0G. In step 8200, under the control of the control a circuit 18, the indicator 26 is read (step 52o).

Here, if the indicator 26 is pointing to the recording unit 100 first, step lit! Go-3)”, the instruction recording section of the indicator 26 will be 100→
200 → 1GG −+ ZGo, write again 1 & part 1
Then, in step 810, it is determined whether the content of the copy counter 24 is "°C". Now, the content of the counter 240 is "I", so a negative determination is made and the process proceeds along the flow of "NOJ" and returns to step 8.
Return to 3. A negative determination is made in step s3, and the process proceeds to step 84K. In step s4, copy number counter 24
It is determined whether or not the 0 content is "2", and if an affirmative determination is made, the process proceeds to step szoo. In step 8300, first, the contents of the indicator 26 llPm! (step 5s00-1), and the instruction 1 fusion III (in this example, record 15

). Then, the indicator 26 is incremented by "2" and the instruction recording section is set to the recording section 200 (step 830G-3).
).

With the above, the estimated number of copies (N-h) of the original manuscript is completed, and the process proceeds to Stella 7S11, where the page counter 25
Subtract rlJY from the 0 content and set the content to "l".

In step s12, ttINJ is checked to see if the content of the counter 280 is "℃", and if a negative determination is made, step 813
Wait for the second person to start copying the manuscript. Here, when the second original is placed on the printer 401 and the start button 22 is pressed, the specified number of copies N=S set in advance by the dial 20 is again set to the copy counter in the control circuit 18. 4 (Stella 7814).

Then, the process returns to step 83 again, and the recording of the second manuscript is performed in the same manner as the eleventh manuscript. That is, first step 520
Copying is performed in all recording units Zoo, 200, and 300 at 0, and the indicator 26 is advanced by 3, and the recording unit 3
Let 00 be the instruction recording section again. Next, step 530G
Then, the recording section 300 and 1OO1 are driven to perform recording, and the indicator z6 is advanced by "2" to change the designated recording section from the recording section s soo to the recording section 200.

After copying 5 copies of the second person's manuscript in the above manner, go to step all again and select rl from the contents of the page counter 25.
J is subtracted, and in step 812, the content of SO is "0".
Determine whether or not. Here, an affirmative determination is made, that is, it is determined that copying of the specified number of copies N=5 of the preset specified number of pages L=2 pages has been completed, and the copying operation ends.

Next, in the case of copying a new original 7.1 copy one after another, the specified original page number L - 2 pages and the specified section clause N = 1 sheet are stored in the counters 25 and 24, respectively (step Sl), steps 82 and 83.

84 V rNOJ flow, step 54
Recording is performed at 00. In this case, recording is performed on indicator 26011 display portion 20G (step 3
400-2). After recording, the indicator 26 is moved to rlJ, and a portion of the instruction is transferred from the recording section 20G to the recording section 200. Therefore, the second page of the manuscript is now recorded in step 8.
400, the recording section 300 records $5, and the indicator 26 is incremented by "1" again, and the carrier placement section moves to record S500.

Furthermore, if one new page of original lllVt is to be copied, an affirmative determination is made in step s2 and the process proceeds to step 8.
In step 8100, the indicator 26 is read (Stella 78100-1), and the instruction recording section 100 is selectively driven to perform recording (step $10).
0-2). Then, in Stella 7B10G-3, rlJ is subtracted from the content of copy counter 24, and the subtraction result is (
'' is determined in step 5100-'4. If the determination is negative, the process returns to step 5100-1 and performs the steps described in instruction record 1110. The counter 24
This is repeated until the content becomes (''. When the content becomes ('', an affirmative determination is made in step 8100-4, the process proceeds to step B100-IK, and the indicator 26 t' rlJ
Then, the recording section 200, which is an instruction recording section, is used, and the copying operation is completed.

In the above explanation, we have described the case where three stages of the recording section v are provided, but of course this is not limited to this only, and as shown in 1E5E, in the case of one stage (n = 1, 2, 3...) O can be similarly applied.

5. In the apparatus of the present invention, multiple stages of recording II
Since the data are used in the order 'eJc', the degree of use of only the specific O recording section will not be high and the degree of fatigue will not increase compared to other recording sections, and the recording section will not be used for a long period of time. Therefore, it is possible to avoid a situation where the recording head becomes clogged and proper recording cannot be performed.
